Abstract: A single-domain antibody or an antigen-binding fragment thereof to Senecavirus A, the single-domain antibody or the antigen-binding fragment thereof being selected from 52 amino acid sequence groups, and each of the 52 amino acid sequence groups including a first variable domain of heavy chain VH-CDR-1, a second variable domain of heavy chain VH-CDR-2, and a third variable domain of heavy chain VH-CDR-3. The first variable domain of heavy chain VH-CDR-1 has an amino acid sequence represented by one of SEQ ID NO: 1-SEQ ID NO: 52. The second variable domain of heavy chain VH-CDR-2 has an amino acid sequence represented by one of SEQ ID NO: 53-SEQ ID NO: 104. The third variable domain of heavy chain VH-CDR-3 has an amino acid sequence represented by one of SEQ ID NO: 105-SEQ ID NO: 156.

Abstract: An optical imaging lens assembly having, sequentially along an optical axis from an object side to an image side, a first lens, having a positive refractive power, an object-side surface of the first lens being a concave surface; a second lens, having a negative refractive power, an image-side surface of the second lens being a convex surface; a third lens, having a refractive power; a fourth lens, having a refractive power; a fifth lens, having a refractive power; a sixth lens, having a refractive power; a seventh lens, having a refractive power; and an eighth lens, having a refractive power.

Abstract: A system for electronically and optically monitoring biological samples, the system including: a multi-well plate having a plurality of wells configured to receive a plurality of biological samples, each of the wells having a set of electrodes and a transparent window on a bottom surface of the well that is free of electrodes; an illumination module configured to illuminate the wells; a cradle configured to receive the multi-well plate, the cradle having an opening on the bottom that exposes the transparent windows of the wells; and an optical imaging module movable across different wells of a same multi-well plate to capture images through the windows.
